M A I N T E N A N C E 514 MAINTENANCE SCHEDULES EMISSION CONTROL SYSTEM MAINTENANCE The Scheduled maintenance services, listed in bold type in this section (Section 8) must be done at the times or mileages specified to assure the continued proper functioning of the emission control system. These, and all other maintenance services included in this manual, should be done to provide best vehicle performance and S reliability. More frequent maintenance may be needed for C vehicles in severe operating conditions, such as dusty H areas and very short trip driving. E D U L E S MAINTENANCE SCHEDULE The oil change indicator system will remind you that it is time to take your vehicle in for scheduled maintenance. The "Change Oil" message will flash in the instrument cluster odometer and a single chime will sound, indicating that an oil change is necessary. Based on engine operation conditions the oil change indicator message will illuminate, this means that service is required for your vehicle. Have your vehicle serviced as soon as possible, within the next 500 miles (805 km). NOTE: • The oil change indicator message will not monitor the time since the last oil change. Change your vehicles oil if it has been 6 months since your last oil change even if the oil change indicator message is NOT illuminated. Inspection and service also should be done anytime a malfunction is suspected. NOTE: Maintenance, replacement, or repair of the emission control devices and systems on your vehicle may be performed by any automotive repair establishment or individual using any automotive part which has been certified pursuant to U.S. EPA or, in the State of California, California Air Resources Board regulations. 8
